FIG. 2 is a diagram of a gesture of an example card for a scan; and

FIG. 3 is a diagram of examples of two-dimensional codes.

DESCRIPTION

The present system and approach may incorporate one or more processors, computers, controllers, user interfaces, wireless and/or wire connections, and/or the like, in an implementation described and/or shown herein.

This description may provide one or more illustrative and specific examples or ways of implementing the present system and approach. There may be numerous other examples or ways of implementing the system and approach.

Aspects of the system or approach may be described in terms of symbols in the drawing. Symbols may have virtually any shape (e.g., a block) and may designate hardware, objects, components, activities, states, steps, procedures, and other items.

A two-dimensional (e.g., two dimension) code may be used in an access control system. A two-dimensional code scanner may decode information that is hidden in the two-dimensional code, and approve or reject the application which had been presupposed. But the scanner might not be able to identify whether the card holder is authorized or legal, in that the scanner might only decode the two-dimensional coded message.

In an access control system application, the scanner may identify not only the message on the card, but also the legality of a card holder. So it may be necessary to add other elements to achieve a goal in the access control system. The present system may provide an easy and economical access control system that scans a two-dimensional code, adds direction, identification, tracks the scanning process, and sets up a maximum retry scanning time in order to enhance the security level. Other features may be added.

When building a two-dimensional code card for a holder, the message on the two-dimensional code card may include information about the card holder, a scanning track (clockwise/anticlockwise rotation), the beginning direction of card (before and at a scan), direction during the scan, and an ending direction of the card (at and after the scan).

With the different card begin-directions, such as during scan directions, the card end-directions, and scan tracks; the card may provide enough combinations for the rotate and direction operations during the scanning process, for many unique identifications of the various cards. Thus, the system may easily void a card identification that may be used by a wrong holder.

In a use scenario, a visitor may get the two-dimensional code which is printed on materials such as paper, and be shown how to operate the scanner at the entry or reception area. Once the visitor intends to enter the secured area, the scanner of the access system may scan the two-dimensional code to check card holder's information, the scan track (rotation) and the card direction. The access application may be approved after all the information pieces are matched with the information pieces presupposed in the access system. Otherwise, the application may be rejected. Also, if the card holder tries more than the preset maximum number of times, the control system may send an alarm to the administrator.

The rotation may mean the rotating the physical or electronic orientation of the card when being scanned or encrypted. When one scans the card having a two-dimensional code, scanner may originally get the information from the two-dimensional code. Further, a physical rotation of a card may also be an encrypted signal based on the two-dimensional code, such as a ninety degree clockwise rotation.

The term “gesture” may refer to a positioning of the card for encryption or scanning. Actually, the gesture may be more a “physical rotation” rather than an “electronic rotation”. While scanning the card, a user may rotate the card physically a certain angle, like ninety (90) degrees clockwise. Also, the card may be just be scanned but will not necessarily be encrypted. The information flow may be just from card to scanner. The scanner might do nothing to the card. Encryption may be an action from a scanner to the card. A new two-dimensional card may be developed with encryption.

A guest, for instance, Leo, may come to a reception desk at a facility and provide his basic information, like his name, whom to visit and zone to visit, for example, zone A. The reception desk may print one card with a two-dimensional code and let Leo know a rotation angle while using the card. The rotation may be a gesture. Leo may want to access zone “A” and thus will show the card in front of the scanner. Meanwhile, Leo may rotate the card with the gesture and be admitted to zone “A”. Leo cannot access zone “B” using this card and gesture. If Leo drops this card and George picks up, George cannot access zone “A” even though he has this card because George does not know the gesture.

An implementation of the present approach may use a QR code but it is not necessarily limited to the QR code. QR code may be just one kind of a two-dimensional code. Reasons for using a two-dimensional code in the present approach is that the two-dimensional code may contain information about guests, besides the card holder, such as a name, addresses, zones to visit, and so forth. The two-dimensional code may need a scanner to decode the information. The scanner may recognize, for example, a rotation angle, direction and other characteristics, which are features of the present system.

Also, other kinds of codes of various sizes may be used in the present system.

To recap, an access control mechanism may incorporate an item having a multidimensional pattern, and an optical scanner that decodes the multidimensional pattern. An entry or exit of s facility or an area may be sought for a holder of the item. The optical scanner upon a scan of the item may decode the multidimensional pattern on the item which has a gesture applied to the item, into a result. If the result from the scanner and the gesture applied to the card meet predetermined criteria, then the entry or exit of the facility or area may be granted to the holder of the item.

The gesture may be applied to the item before, during or after the scan.

The gesture may be one or more actions selected from a group incorporating a track of clockwise rotation, a track of counterclockwise rotation, a direction of the item at a beginning of the scan, a direction of the item during the scan, and a direction of the item at an ending of the scan.

The item may be a card or a badge.

The multidimensional pattern may be a two-dimensional pattern.

The result may contain information or data about the holder of the item.

The result may incorporate information about the gesture and the result may be reviewed by the scanner to determine whether the conditions for the gesture are met during the scan.

A number of attempted determinations to have the conditions for the gesture be met during a scan may be limited to Y. Y may be a predetermined number.

An approach for controlling access may incorporate writing information on a card in a two-dimensional code, and scanning the card to read the information from the two-dimensional code on the card. The information may incorporate data about a card holder and a description of a gesture needed for scanning the card.

A gesture may incorporate one or more items selected from a group having a direction of the card at a beginning portion of a scan, a direction of the card during the scan, a direction of the card at an ending portion of the scan, a scanning track of clockwise rotation, and a scanning track of counter-clockwise rotation.

The two-dimensional code may be selected from a group incorporating HanXin codes, quick response (QR) codes and Aztec codes.

If the card is accepted upon its scan by a scanner, then the card holder may gain access to an entity controlled by the scanner. For the card to be accepted upon its scan, the information read from the two-dimensional code of the card may match information expected from a scan of the card and the gesture may match a gesture expected from the scan of the card. The information expected and the gesture expected may be stored in the scanner for comparison with information and gesture scanned from a two dimensional code of a card for a purpose of validating the card and/or a holder of the card.

An access system may incorporate a card scanner and a card having a two-dimensional code imprinted on the card. The card may have an encrypted gesture for scanning by a scanner. The two-dimensional code and encrypted gesture may have to be recognized in the scanner as a predetermined match to recognize a holder to be in legitimate possession of the card.

A gesture may incorporate a change of orientation of the card while the card moves across the scanner.

The orientation may be a rotation of the card during a movement of the card across the scanner. The gesture may further incorporate a direction of the card during the movement of the card across the scanner.

The two-dimensional code may incorporate information about a card holder and what the gesture must be for acceptance of the card to grant an access to or egress from a facility or area.

A number of attempts to scan the card and obtain acceptance of the card may be limited to X. X may be a predetermined number.

The gesture may indicate to the scanner of the card whether the holder of the card is authorized to hold the card according to information deciphered from the two-dimensional code.

A gesture may incorporate a beginning orientation of the card upon a scan, an orientation of the card during the scan, and an ending orientation of the card upon a termination of the scan.

The two-dimensional code may be selected from a group incorporating HanXin codes, quick response (QR) codes and Aztec codes.
